Load bearing mechanism for laminated mold

The present invention relates to a load bearing mechanism, and more particularly to a load bearing mechanism for carrying a laminated mold.

A laminated mold is a new type of mold that is distinguished from a common single-sided mold. Compared with ordinary single-sided molds, laminated molds have the advantages of high output, low production and maintenance costs, and low footprint. Over the decades, laminated molds have continued to evolve in the production of packaging products and small parts, and today they are used in large-tonnage molding machines to form large parts.

The laminated mold combines at least two conventional injection molding modules, which typically include a movable mold, an intermediate runner plate, a fixed mold, and a hot runner system. The movable mold and the fixed mold are respectively fixed on the movable template and the fixed template of the injection molding machine, and the intermediate runner plate is supported by the supporting mechanism. Since the laminated mold further has a plurality of parting surfaces and a corresponding plurality of ejector mechanisms, an interlocking mechanism is also arranged between the movable mold, the intermediate runner plate and the fixed mold to open the various parting surfaces, such as gears. Rack mechanism, crank mechanism and tie rod mechanism. After the closed-mold injection molding is completed, the mold is opened. Under the action of the interlocking mechanism, the intermediate runner plate and the bearing mechanism move along with the moving mold until the parting surfaces are opened, and then the ejector mechanism takes out the forming parts. Molded parts in the profile cavity.

The support mechanism for supporting the intermediate runner plate in the conventional laminated mold is a slide rail fixed to the molding machine. The rail passes through the intermediate runner plate and supports the intermediate runner plate on the forming machine. If the laminating mold needs to be replaced, the intermediate sprue plate can be replaced only after the sliding rail is withdrawn from the intermediate sprue plate, so it takes time and effort to replace the mold.

In order to overcome the above drawbacks, the bearing mechanism generally used for the laminating mold is a separate mechanism independent of the sliding rail, which is respectively connected with the intermediate runner plate and the sliding rail, so that the intermediate runner plate can slide along the sliding rail. A conventional carrier mechanism is two support blocks. The two support blocks are symmetrically disposed on both sides of the intermediate runner plate, and the intermediate runner plate is fixed thereto by screws and connecting keys. The two support blocks are placed on the slide rail together with the intermediate runner plate, and the support block supports the intermediate runner plate to slide along the slide rail.

The carrier mechanism is adapted to carry a smaller weight of the intermediate runner plate to form small parts. However, when a large-sized component needs to be formed, the supporting mechanism can be required to carry a large weight, and the support block of the above-mentioned supporting mechanism and the intermediate runner plate are screwed and keyed, so that the load of the laminated mold directly acts on the screw. And the connection button. Since the supporting force of the screw and the connecting key is extremely limited, the bearing mechanism has a small bearing capacity and cannot be applied to a large-tonnage forming machine, and cannot carry a large-scale laminated mold to form a large-sized component.

In view of this, it is necessary to provide a load-bearing mechanism for a laminated mold having a large bearing capacity.
